Do you want to know from which country who sent you a Email or gave you a call ? There are two simple ways.

One way is judging from their Country domains which formally called country code top-level domain (ccTLD) . If the contact person’s email’s domain is a country code domain, you will can find out which country he/she came from through the following list . For example, if you received an Email with country domain of .qa, then I can say this sender probably came from Qatar. But this method is invalid for original top-level domains like .com, .net and .org . This method is not workable with country domains sometimes. For example, my domain is plywood.cc. While .cc domain is the ccTLD for Cocos (Keeling) Islands, but I’m from China.

Another way is judging from from their phone number’s country code. Sometimes you may miss a call but want to know where the call came from. Then you can check their country’s calling code . For example, as a plywood exporter, if you missed a call with calling code +971, then you will know a potential buyer from United Arab Emirates may give you a call.

It is generally believed that hardwood cut in winter is better than that felled in the spring and summer. People usually think winter-cut hardwood is more durable, tough and has less splits and more beautiful wood grains.

It is thought that "winter-cut hardwood have less sap which may affect the good properties of wood, in spring and summer some substances in trees are dissolved out for plant growth and will be restored in autumn".

Experimental data shows that sapwood has only slight differences between winter and other seasons while the dead heartwood has not changes in the whole year. Moreover, winter-cut hardwood is not drier.
